PLAIN TEXT PHP: $guid = md5(uniqid(rand(), true)); md5 sanitizes the ID and limits it to 32 characters. uniqid generates a random ID based on your server's time, etc. rand() is prefixed onto the ID - thus enhancing the ID's uniqueness. true tells uniqid() to make use of "more entropy" - again enhancing the ID's uniqueness.

I prefer initialising all my scripts through a bootstrap script that in turn reads a configuration file. I tend to re-use a common set of configuration parameters. PLAIN TEXT PHP: define('DEBUG_PROJECT', false); define('DISPLAY_ERRORS', true);</code> /** * E-mail send/receive related * / define('EMAIL_CONTACT_ADDRESS', 'webmaster@mysite.com'); define('EMAIL_SERVER_FROM_IDENTITY', 'MySite Webmaster'); define('EMAIL_WEB_ADMINISTRATOR', 'admin@mysite.com'); /** * Time-related */ //EOT [...]

A robots.txt file in your web site's root directory informs robots who follow the Robots Exclusion Protocol on which areas of your site can be indexed and which areas cannot be indexed. A simple robots.txt implementation tells all robots that your entire site is indexable: User-agent: * Disallow: But be careful not to do the [...]

BFD (brute force detector) is an excellent package by rfxnetworks that works hand-in-hand with the APF firewall package to automatically detect and put an end to brute force access attempts. BFD works by monitoring for excessive access attempts via ssh. If it does detect attempts, it places the offender's IP in APF's deny hosts file. [...]

So I've installed WordPress and it's time to clean up the installation. Like any open source package, security vulnerabilities are well documented and open to exploitation by anyone who can read. So here are some of the steps I have taken to secure copies of WordPress. cd /home/blogger/www/blog/ rm -f wp-config-sample.php More to come... Tweet
